FIG. 8 is 'a fragmentary view of a modified form of marine driveapparatus embodying the present invention.

As representing the preferred embodiment of the present invention, amarine drive apparatus 10 is illustrated in the drawings. The marinedrive apparatus 10 includes an engine 1d of any suitable or well-knownconstruction mounted within a boat 12 and for providing the power forpowering the boat through the water. The marine drive apparatus 10 alsoincludes an engine mount adaptor sleeve 13 secured at one end to theengine 11, and extending through an opening 1 in a transom 15 of theboat, and an outboard power leg 16 releasably secured within the enginemount adaptor sleeve 13 and carrying a propeller 17 for propelling theboat through water. The outboard power leg 16, as is well known,includes a suitable drive mechanism including a shaft I19 releasablyconnected to the engine 11 for rotating the propeller 17.

The outboard power leg 16 is supported on the boat for rotary orswiveling movement relative to the boat in order to position theoutboard power leg properly for trailering, storage, changing ofpropellers while the boat is in the water, etc. The outboard power legis also supported for removal from the boat by movement axially of itsaxis of rotation. The outboard power leg 16 is supported for its rotaryand axial movements by the engine mount adaptor sleeve 13 andspecifically is supported thereby for rotation about the axis of theengine mount adaptor sleeve 13 and for movement axially along the axis20 relative to the engine mount adaptor sleeve. The outboard power leg16 includes a forward joint housing member 21 which extends through anaxial opening 22 in the engine mount adaptor sleeve 13 and cooperatestherewith to support the outboard power leg. The forward joint housingmember 21 is rotatably supported in the opening 22 in the adaptor sleeveand is axially movable relative thereto.

The outboard power leg 16 and the propeller 17 carried thereby areadapted to be swiveled or rotated about the axis 20 and locked in anyone of four positions, namely, a first position in which the outboardpower leg 16 and the propeller 17 extends vertically downwardly, asecond position in which the outboard power leg and the propeller arelocated 90 in a counterclockwise direction from its first position, athird position, shown in the dot-dash lines in FIG. 1, in which theoutboard power leg 16 and the propeller 17 carried thereby are in avertical upwardly extending position spaced 180 from the firstposit-ion, and a fourth position in which the outboard power leg 16 andthe propeller 17 are positioned 180 from the second position.

The engine mount adaptor sleeve 13 carries a suitable locking or latchmeans for releasably securing the forward joint housing member 21 of theoutboard power leg 16 Within the engine mount adaptor sleeve 13 in anyof the above noted positions. The locking means 25 comprises a pin orlocking member 26 positioned in an opening 27 in the engine mountadaptor sleeve 13. The forward joint housing 21 of the outboard powerleg 16 is-provided with a plurality of circumferentially spaced openings29; best seen in FIG. 7, preferably four such openings spaced 90 apart,located adjacent the forward end thereof and into which the pin 26 mayextend for locking the forward joint housing 21 in position andpreventing the housing 21 from rotating or moving axially relative tothe adaptor sleeve 13. In each of the four above mentioned positions towhich the outboard power leg 16 may be rotated, one of the openings 29will be aligned with the pin 26 so that the outboard power leg 16 andthe propeller 17 may be locked in that position.

The pin member 26 may be removed from the opening 29 in the forwardjoint housing 21 in which it is located by lifting it upwardly to aposition, indicated by the solid lines in FIG. 3, in which rotation ofthe forward joint housing 21 and the outboard power leg 16 about theaxis 20 relative to the adaptor sleeve 13 is permitted. In this positionthe pin member 26 rides on the outer surface 30 of the forward jointhousing 21, which surface is radially spaced from the inner surface 31of the engine mount adaptor sleeve 13, as the outboard power leg 16 andthe forward joint housing 21 thereof are rotated relative to the annularsleeve 13 and falls into the next adjacent opening 29 and locks theforward joint housing 21 against further rotation. When the pin member26 is in the solid line position shown in FIG. 3, axial movement of thehousing 21 in a rearward direction or to the left, as viewed in FIG. 3,relative to the engine mount adaptor sleeve 13 is prevented by anannular shoulder 32 formed on the forward portion of the forward jointhousing 21 which engages the pin 26. The pin 26 is also removable to aposition indicated by the dot-dash lines in FIG. 3 wherein the lower endof the pin member is spaced upwardly from the shoulder 32 of the forwardjoint housing 21 to permit the forward joint housing 21 to be movedaxially relative to the adaptor sleeve 13 and toward the transom 15 ofthe boat.

According to the present invention, a suitable drive mechanism,indicated generally by reference character 35, is provided for rotatingthe outboard power leg 16 relative to the engine mount adaptor sleeve 13when the pin member 26 is in the full line position shown in FIG. 3. Thedrive mechanism 35 includes a suitable driving member 36 which isreleasably connected to the forward joint housing 21 in order to effectrotary movement or rotation of the forward joint housing 21 and isreadily disconnectable therefrom to permit removal of the forward jointhousing 21 from the driving member 36, as will be apparent from thedescription hereinbelow.

The driving member 36, in the illustrated embodiment, includes asprocket wheel 37 having an annular plate or member 38 secured theretoin any suitable manner, preferably by being welded to the sprocket wheel37. The driving member 36 is disposed within an annular recess orcounterbore 40 formed in the forward end 41 of the engine mount adaptorsleeve 13, with the periphery 42 of the plate 38 thereof being spacedfrom the annular inner wall 43 of the recess or counterbore 40 toprovide for smooth rotation thereof. A suitable snap ring 45 is providedfor holding the driving member 36 within the recess 40. The drivingmember 36 is provided with a central opening 46 therethrough throughwhich the shaft 19 extends, and the sprocket wheel 37 and the plate 33are provided with a plurality of annularly spaced aligned openings 48therearound.

The forward joint housing 21 at its forward end 41 is provided with aplurality of annularly spaced axially extending openings 49 whichreceive pin members 50. The pin members 51) are press fitted orotherwise fixedly secured within the openings 49 and project forwardlyof the forward end 4-1. The spacing and the number of the pin members 50correspond to the spacing and the number of openings 48 contained withinthe driving member 36. When the outboard power leg 16 is moved'axiallyrelative to the engine mount adaptor sleeve 13, to the right, as viewedin FIG. 3, and to its operative position on the boat, the pin members 50carried thereby are received within the openings 48 and cooperatetherewith to effect a driving connection between the forward jointhousing 21 of the outboard power leg 16 and the driving member 36. Thepin members 50 are readily removable or disconnecta'ble from theopenings 48 in the driving member 36 in response to axial movement ofthe forward joint housing 21 relative to the engine mount adaptor sleeve13 away from the driving member 36 and to the left, as viewed in FIG. 3.Thus, the pin member 50 and the portions of the drive member 36 definingthe openings 48 therein constitute cooperating means for effecting adriving connection in response to movement of the outboard power leg 16to its operative position and are disconnectable to in response tomovement from its operative position, as shown by the phantom lines inFIG. 3.

The pin members St) are preferably tapered at their forward end portions51 to facilitate entry into the openings 43 of the driving member 36 andcoaxially align the driving member 36 and the forward joint housingmember 21 so that the outer periphery 42 of the plate member 38 will bespaced from the inner wall 43 to provide for smooth rotation of thedriving member 36. It will be apparent from the above description, thatupon rotation of the driving member 36, the forward joint housing 21 andthe outboard power leg 16 will be rotated therewith, presuming, ofcourse, that the pin member 26 has been moved from its locking positionin one of the openings 29.

The drive mechanism 35 further includes a drive arrangement for rotatingthe driving member 36 comprising a chain 53 trained around the sprocketwheel 37 and around a sprocket wheel 54 rotatably supported in a housing55 located adjacent to and adjustably mounted on one side of a housing56 containing portions of the engine 11. The engine mount adaptor sleeve13 is provided with a pair of tangent openings 57 adjacent its forwardend through which the chain 53 extends. It can be seen therefore thatupon movement of the chain 53,

the sprocket wheel 37 will be rotated to rotate the outboard power leg16.

The housing 55 which supports the sprocket wheel 54 has a bridge portion58 extending from the main portion 59 of the housing 35 and definingwith the main portion 59 of the housing 55 a generally U-shaped space 60in which the sprocket wheel 54 is disposed. The sprocket wheel 54 isfixed on a shaft 61 which is rotatably supported at one end by suitablebearings in the main portion 59 of the housing 55 and rotatablysupported at the other end by suitable hearings in the bridge portion58. Also fixed to the shaft 61 in the housing 55 is a worm wheel 62which is in constant mesh with a worm gear 63 rotatably supported in thehousing 55 and fixed to an output shaft 64 of a motor 65. The shaft 64extends substantially vertically, as shown in the drawings. The motor 65may be of any suitable construction, and preferably is an electricmotor. The motor 65 is manually actuated by any suitable controlarrangement positioned so as to be convenient to the operator of theboat.

From the above description, it should be readily apparent that uponenergization of the motor 65 the sprocket wheel 54 will be rotatedcausing rotation of the sprocket wheel 37 of the driving member 36 androtation of the outboard power leg 16 relative to the engine adaptorsleeve 13 when the outboard power leg 16 is connected with the drivingmember 36.

When it is desired to rotate the outboard power leg 16 to a differentposition, it is difficult to stop the motor 65 at the precise pointwhere the pin 26 is aligned with an opening 29 of the forward jointhousing 21 and thus, the motor 65 after the pin 26 has dropped into anopening 29 continues to apply a torque force to the driving member 36tending to move the forward joint housing member 21 into bindingengagement with the pin member 26. Because of this binding engagement,it is difficult to remove the pin 26 from! the opening 29 at asubsequent time in order to provide for further rotation or swiveling ofthe outboard power leg 16. In order to reduce this binding force, asuitable handwheel 70 connected to a projecting shaft portion 71 of theoutput shaft 64 of the motor 65 is provided. The handwheel 70 uponrotation effects rotation of the output shaft 64. It is readily apparentthat upon a slight rotation of the handwheel 70, the driving member 36will be likewise rotated, to relieve the binding force on the pin member26 exerted by the forward joint housing 21.

For the purposes of enabling the chain 53 to be tensioned, the housing55 is adjtusta bly mounted to the housing 56 of the engine 11. To thisend the housing 55 has an arm 75 having one end rigidly secured to thehousing 55 at its upper portion, as viewed in the drawings, and theother end pivot-ally connected to the housing 56 by a pivot pin 76 forpivotable movement about the axis 77 of the pin 76. The housing 55 atits lower side has a projecting portion 80 having opposite ends 82 and83 provided with threaded openings 84 and 85, in which suitable screw orbolt members 86 and 87, respectively, are threadably secured. Thehousing 55 is adjtustably positioned with respect to the housing 56 byconnecting members 88 and 89 having one end pivotally connected to thehousing 58 by pivot pins 90 and 91 and the other end provided with slots92 and 93 through which the bolts 86 and 87 extend, respectively. Byloosening the bolts 86 and 87, the housing 55 may be pivoted about theaxis 77 either toward or away from the driving member 36 in order toeffect a change in the tension in the chain 53. The housing 55 is heldin the positionto which it is pivoted by tightening the bolts 86 and 87.

FIG. 8 shows a modified embodiment of the present invention which isgenerally similar to the embodiment shown in FIGS. 1-7 except that acrank mechanism 95 is substituted for the motor means 65. In otherrespects the modified embodiment is the same as the embodimentillustrated in FIGS. 1-7 and the same reference characters have beenapplied to identical or substantially identical parts. The crankmechanism is utilized to manually actuate the driving member 36 andcomprises a handgrip 96 connected at one end to a suitable crank member97 which in turn is connected at its other end through a suitableuniversal type coupling 98 to the shaft 64 on which the Worm gear 63 isfixed. It should be apparent that upon rotation of the crank member 97,the worm gear 63 is rotated. Rotation of the worm gear 63 in turneffects rotation of the driving member 36 and the outboard power leg 16,in a manner hereinbefore described in connection with the modificationshown in FIGS. 1-7.

Although in the preferred embodiment of the invention, the outboardpower leg 16 may be rotated and locked in any one of the fourabove-named positions, it will, of course, be understood that anysuitable spacing or number of openings 29 may be provided so that theoutboard power leg can be swiveled to any desired position and lockedin-place. It should further be understood that the preferred embodimentsof the present invention have been described hereinabove in considerabledetail and that certain modifications, changes, and adaptations may bemade therein by those skilled in the art, and it is hereby intended tocover all such changes, modifications, and adaptations made thereincoming within the scope of the appended claims.
